We have here a list of eighty-nine species, which, 

 according to the best authorities, are, in the jDresent state 

 of our knowledge, peculiar to Britain. It is a curious fact 

 that no less than fifty of these have been described more 

 than twenty-five years ; and as during all that time they 

 have not been recognised on the continent, notwith- 

 standing that good coloured figures exist of almost all of 

 them, it seems highly probable that many of them are 

 really confined to our island. At the same time we must 

 not apply this argument too rigidly, for the very day before 

 my visit to Mr. Stainton he had received a letter from 

 Professor Zeller announcing the discovery on the continent 

 of a species of our last family, Pterophorina, which for 

 more than forty years had been considered to be exclu- 

 sively British. This insect, Platyptilia similidactyla 

 (FkropJiorus isodadylus, Stainton's Manual), had been 

 taken rarely in the extreme north and south of our islands 

 — Teignmouth and Orkney, a fact which seemed some- 

 what indicative of its being a straggler. Again, seven of 

 the species are unique, that is, have only been captured 

 once ; and it may be supposed that, as they are so rare as 

 to have been found only once in England, they may be all
